Place crushed tomatoes, tomato sauce, broth, onion, garlic, Italian seasoning, salt, pepper and bay leaf into a slow cooker.
Cook for 4 hours on low.
When there are 20 minutes left on the cook time for the soup, make the croutons:
Preheat oven to 350 degrees.
Line a sheet pan with parchment paper or foil.
Place gluten-free bread cubes on sheet.
Spray with olive oil and sprinkle with salt and pepper and toss with your hands.
Sprinkle grated Violife Just like Parmesan and place in oven for 15 minutes, tossing at least once, until croutons are golden brown.
Remove bay leaf from soup, then add beans and coconut milk.
Use an immersion blender to puree soup (or, working in batches, puree it in a conventional blender).
Pour soup into bowls, top with croutons, and serve.
